Be aware of humidity problems as soon as they start with this humidity sensor that triggers I/O Linc-connected lamps to flash. The Minotaur Engineering IHSV@ Humidity Sensor/Controller for INSTEON I/O Linc triggers based on a humidity level that you set (15% to 95%) and sends a signal to any INSTEON receiver in range via an I/O Linc (sold separately). The sensor is completely self contained and uses a solid state transducer preset at the factory. There are three leads extending from the sensor. The sensor should be placed in a location that will protect it from moisture and direct sun to accurately reflect the ambient humidity.

The INSTEON Humidity Sensor/Controller connects to the I/O Linc unit via three leads on a 5-foot cable. The IHSV2 senses the ambient room humidity using a sophisticated semiconductor device. It draws power from the I/O Linc module and triggers based on a user setting. Humidity will vary from room to room and from one area of a room to another. Ventilation and airflow will affect relative humidity. The IHSV2 has a delay/ spread of about 3% RH. Always allow enough time for the sensor to acclimate to current room conditions before expecting it to trigger accurately.

NOTE: Observe polarity in connecting to the I/O Linc. Incorrect wiring to the I/O Linc can destroy the device. If the I/O Linc and/ or INSTEON Responder have been used previously, they need to be set back to their factory settings prior to use. For residential use only. Do not submerge. Best operating temperature range is 55&deg F to 95&deg F.

1) Connect the Shiny Metal sensor wire to the I/O Linc "GND" Terminal (2nd from the left screw terminal.)

2) Connect the Black wire to the I/O Linc "SENSOR" Terminal (3rd from the left screw terminal.)

3) Connect the Red wire to the I/O Linc "5v" Terminal (1st from the left screw terminal.)

4) Plug your I/O Linc into an un-switched outlet. (The I/O Linc LED will come on.)

5) Using a small screwdriver on the blue trimmer potentiometer located on the exterior of the sensor, turn the dial all the way to the left (counterclockwise) to get the humidity to trigger a device ON at or above the set humidity (Or OFF below a set humidity).

6) Press and hold the I/O Linc Set button until it beeps (about 3 seconds.)

8) Now Press and hold the Set button on your INSTEON Responder (the device you wish to control) for at least 3 seconds. (The I/O Linc will beep and its Status LED will return to steady "on" to confirm linking.) The INSTEON device will be "triggered" based on being at a higher humidity than selected.

9) Plug devices you wish to control into your Insteon Responder.

10) Set your trigger humidity based on the instructions on the next page.

New design adds LED for trigger status. Very handy for setup and visual reference. Good!

New form factor is excellent. Now has an LED to help set the trigger point as well as tell you when it has triggered. Nice addition.

After a few days of slight adjustments, I have it working quite well.

Works well. More sensitive than I thought it would be which in the end was better for what I wanted to do.

I tried one of these to sense conditions in a portion of my attic. It had been up there at least 5 months and I had forgotten about it. Suddenly it triggered exactly as planned. Good device and would order again.
